Flash butt welding is.......
Answer: D
Flash butt welding is resistance welding.
The two ends to be joined are clamped and brought lightly together with current flowing. Contact at high points causes flashing (arcing and expulsion of molten metal) until the ends are heated through; they are then forged together under heavy pressure. The heat comes from the current through the joint's resistance, so it belongs with resistance welding, like spot and seam welding.
It uses no gas flame and is not an arc welding process with either polarity.
